IRA O. PERRING, OF KALAIVIAZOO, MICHIGAN.

CAMERA.

To all whom it may concern:

Be it known that I, IRA O. PERRING, a citizen of the United States,residing in the city and county of Kalamazoo, State of Michigan, haveinvented certain new and useful Improvements in Cameras, of which thefollowing is a specification.

This invention relates to improvements in panoramic cameras.

The main objects of this invention are: First, to provide an improvedpanoramic camera which is very simple in its operation, and, at the sametime, produces very satisfactory results. Second, to provide an improvedpanoramic camera in which the shutter is automatically opened andclosed. Third, to provide in a panoramic camera an improved means forshifting the films. Fourth, to provide an improved panoramic camerawhich is comparatively simple and economical in structure and one whichis not likely to get out of repair in use.

Further objects, and objects relat-.ing to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following` specification.

Specification of Letters Patent. Patented NOV. 30, 1909.

Application filed January 11, 1909.

Serial No. 471,644.

Tn the drawing, the sectional views are taken looking in the directiono'f the little arrows at the ends of the section lines, and similarnumerals of reference refer to similar parts throughout the severalviews.

Referring to the drawing, the base 1 is provided with a central post 2and with a peripheral way 3, on which the casing 4 is mounted torevolve. The post 2 is preferably provided with a threaded hole 5,adapted to receive the screw of a tripod.

The casing L is preferably cylindrical and formed of metal and providedwith a removable cover 6, having a downwardly-projecting flange adaptedto receive the upper end of the casing. The casing is provided in oneside with a shutter opening 7. This opening is preferably provided witha slide closure or door 8, arranged in the vertical slides 9,-see Figs.1 and 3.

The shutter 10 is preferably arranged in the horizontally-arrangedguides 11, so as to move horizontally in opening and closing. The casing4l: is driven or revolved by a spring' 12, one end of which is secured,as at 13, to the base post 2, and the other end by means of the pin 14to the bottom of the casing.

By turning the casing in one direction, the spring is wound, and, whenreleased, it will revolve the casing in the opposite direction. Thecasing is held in its set position by means of the lever 15, which ispivoted at 16 on the plate 22 secured to the inside of th-e casing, itslower end being arranged through a slot 17 so that it projects into thebase, its upper end being connected to the shutter 10.

The connection for the lever 15 to the shutter preferably consists ofthe slot 17 in the upper end of the lever which engages a pin 19 on theshutter. A spring 2O is provided for opening the shutter when the leverl5 is released from the stop 21. The spring 20 is secured at one end tothe plate 22 on which the lever ispivoted and its free end arranged toengage the upper end of the lever, as clearly appears in Fig. 9.

The trip stop 21 is pivoted at 23 on the bottom of the base and is heldnormally in position to engage the lever by means of the coiled spring24. hen the lever engages this stop, the casing is not only held, butthe shutter is closed, owing to the spring 12 ,being of greater strengththan the spring 20.

As soon, however, as the lever is released by the tripping of the stop,the spring 2() will open the shutter.

l preferably actuate the trip 2l by means of an engine consisting of arcylinder 25 having a plunger 26 therein, the plunger being provided witha pin 2T on its inner end adapted to engage the pivoted stop. Theplunger is pneumatically actuated by any suitable means, as by the handbulb 2S, as is common practice, the bulb being connected by means of thetube 29 to the outer end of the cylinder. The cylinder is preferablyprovided with an exhaust port 30, which allows the escape of air whenthe plunger reaches the inner end of its stroke, thereby allowing it toreturn to permit the stop 2l to swing into its engaging position withoutthe necessity of manipulating the bulb 2S to return it. This feature isdesirable on account of the rapidity with which the casing revolves,which would `render it ditlicult to manually manipulate the engine toreturn the stop to its engaging position.

The lens box 3l is preferably made up of triangularly shaped side walls,thereby forming a body hexagonal in cross section and expandedvertically and tapered horizontally toward the rear, as clearly appearsfrom the drawing.

The rear wall 32 is provided with a narrow vertical slit-like opening33. The front wall 34 is preferably arranged to project at each side ofthe side walls, as is illustrated, to provide means for supporting thelens box in position, and also for the attachment of the lihn supportingand winding mechanism. The easing 4 is preferably provided with a pairof vertical strips 35, secured on its inner Wall and coacting with thewall of the casing to form vertical grooves adapted to receive the endsof the front wall of the lens box-see Fig. 4. The bottom of the casingis preferably provided with an upwardlyprojecting flange 3G againstwhich the lower end of the wall 34 rests when the lens box is in thecasing, and the casing cover is preferably provided with a flange-likestrip 37 adapted to engage the upper end of the casing when it is inposition.

The lenses 3S are supported by suitable holders 3f) in the lens tube 40,which is mounted on the front wall of lens plate 34 in the lens box. Iillustrate herein a double lens formed and arranged to secure thesocalled universal focus, as I am enabled to secure the best generalresults with such lenses. It is obvious, however, that any form orarrangement of lenses desired might be used.

The film delivery roller 41 is arranged in one side of the box and thefilm receiving roller 42 of the lens box is arranged on the otherside,-see Fig. 4. These rollers are supported by brackets 43 and 44, the

brackets 43 having upwardly -projecting bearing pins or studs 45thereon, while the brackets 44 have downwardly projecting bearing pinsor studs 46. These brackets are provided with slots 47 so that they maybe slidably secured to the wall b v means of the screw 4S engaging theslots. Coiled springs 49 are provided for yieldingly holding thejournals in the rollers.

The film 50 is preferably provided with its usual protecting strip 5l.The lilm is passed from the delivery roll rearwardly over the guiderollers 52, which are arranged to deliver the lilm across the opening1j?) of the lens box, the film being passed under the retaining plate 53which holds it against the rear wall of the lens box, see Fig. 4.

The guide rollers 52 are journaled in the cross pieces mounted on therear end of the lens box. lThe lilm receiving roller 42 is driven towind up the lihn by means of the gear 55, which is mounted on a bracket5G, projecting from the front wall 34 of the lens box. This gear isdriven by the spring' 57, a suitable ratchet 5S and dog 5f) beingprovided for connecting the wheel to the winding spindle (30, which lpreferably provide with a suitable cross pin 61 to receive the windingkey. The gear is connected by the pinions (32 to the driving bearing`stud of the film receiving roller, so that the same is driven to wind upthe film.

The film is fed by means of the feed roller (3B, which is journaled insuitable brackets 64 mounted on the casing. On the lower end of theshaft (S5 of the feed roller is a gear GG which is arranged to mesh withthe gear (S7 secured to the base, so that, as the casing is revolved,the gear 6G, traveling around the lixed gear G7, drives the feed rollerand times the feeding of the film with the movement of the casing. Thisconnection is clearly illustrated in F ig. (i. The pressure roller 68 isarranged to coact with the feed roller G8 in feeding' the film,-that is,it holds the lilm against the feed roller with the desired friction sothat it is fed thereby. This pressure roller G8 is adj ustably mountedso that it may be thrown into and out of its operative position. This Ipreferably accomplish by mounting its bearings on the swinging arms (i9,which are pivoted at 7() on the bracket 7l, which is secured to the sideof the lens box, as clearly appears in Figs. G and 7. The arms (39 areswung to bring the roller into its operative position by means of therock shaft 72, which is provided with cams 73 which are adapted toengage the arms and swing them to the position illustrated in Figs. and7. Then the rock shaft is turned to release the pressure roller, it isswung out of its operative position by means of the spring 74. The rockshaft 72 is preferably operated by means of a key 7 5 adapted to beinserted through the llO cover of the casing. This rock shaft is alsopreferably arranged to control the locking dog 76 for the gear 55, thelocking dog being pivoted at 7 7 on the bracket 7 8, so that its end isengaged by the cam 7 9 on the rock shaft. rlhe dog 7 6 is thrown out ofits engaging position by means of the spring 80. By thus arranging andconnecting the parts, when the pressure roller is thrown into itsoperative position, the winding means for the receiving film roller isreleased so that, when the camera is actuated to release the trip dog2l, the film is automatically fed and wound up, as the casing revolves.

To regulate the length or extent of the view, I provide an adjustablestop 81, which maybe inserted into the holes 82 provided therefor in thebase to engage the lever 15, thereby stopping the casing and closing theshutter, the same as though the casing had made its complete revolutionand the lever engaged the trip stop 21. 1t is obvious that theseadjustable trip stops 81 may be located as desired.

1 have, in my structure illustrated, provided three of the trip stops sothat views may be taken covering an arc of ninety, one hundred eighty,and two hundred seventy, or a complete circle, as desired.

My improved camera is very quickly and easily operated and produces verysatisfactory results. rllhe casing revolves onl a central pivot, so thatthe relative position of the lens and the film is maintained throughoutthe complete operation of the camera.

By providing the narrow opening 33 a clear, distinct negative issecured.

I have illustrated and described my improved camera in detail in theform preferred by me on account of the convenience in its operation andalso in the manufacture and assembling of the parts. 1 am aware,

however, that it is capable of very considerable variation in structuraldetails without departing from my invention, and desire to be understoodas claiming the same specifically as well as broadly.
